To find the sum by making a ten:
Step 1: Add 9 and 1
9 + 1 = 10
Step 2: Add 10 to 5
10 + 5 = 15
Therefore, 9 + 5 = 15 by making a ten.
To find the sum by making a hundred:
Step 1: Add 9 and 1
9 + 1 = 10
Step 2: Add 100 to 10
100 + 10 = 110
Step 3: Add 110 to 5
110 + 5 = 115
Therefore, 9 + 5 = 115 by making a hundred.
To find the sum by making a thousand:
Step 1: Add 9 and 1
9 + 1 = 10
Step 2: Add 1000 to 10
1000 + 10 = 1010
Step 3: Add 1010 to 5
1010 + 5 = 1015
Therefore, 9 + 5 = 1015 by making a thousand.
To find the sum by making a ten, hundred, or thousand, you can use the concept of place value.
For the equation 9 + 5 = __:
1. First, you can find the sum by making a ten. Since 9 + 1 equals 10, you can take 1 from the 5 and add it to the 9. This gives us 10 + 4 = 14 as the sum by making a ten.
2. Next, you can find the sum by making a hundred. Since there are no additional digits in this equation, we cannot make a hundred. Hence, we move on to the next step.
3. Finally, you can find the sum by making a thousand. Again, since there are no additional digits, we cannot make a thousand. Therefore, we move on.
So, the sum for the equation 9 + 5 is 14 by making a ten, and the other two steps (making a hundred or a thousand) do not apply in this case.
